A few years ago I wrote a chapter of Jazz Aotearoa, a book about New Zealand jazz music history, discussing the free improvisation and avant-garde jazz scene in Wellington at the turn of the millennium.
in the non-idiomatic idiom in Norway is a collection of improvised instrumental music with some of the musicians in that scene, from the point of view of my own attempts as an untrained outsider to fit in with these advanced jazz players – including Jeff Henderson, Blair Latham , Paul Winstanley, Dan Beban, Julie Bevan and more.
It was recorded in Wellington in two halves, in 1999
Simon O’Rorke – percussion
Paul Winstanley – synth bass
Blair Latham – alto sax
Jeff Henderson – clarinet
Bridget Kelly – tenor sax
Dan Beban – electric guitar
Dave Edwards – electric and acoustic guitars
and 2014, to show an evolution.
Simon O’Rorke – synthesisers
Blair Latham – bass clarinet
Julie Bevan – acoustic guitar
Michael Hall – alto sax
Chris Prosser – violin
Dave Edwards – bass, electronics, tenor sax
Free improvisation is a genre of music with a self-explanatory name. Nothing is planned in advance, and the performers create the music on the spot by responding to what the others are doing in that moment.
Its historical roots are in the free jazz of the 1960s, but it’s since expanded to include influences from outside the jazz tradition entirely (just as well since I don’t have proper jazz chops). Often there may no regular beat and no key signatures or conventional melody – hence “the non-idiomatic idiom”.
This kind of free improvisation differs from that of The Winter, which is a regular trio with its own particular flavour, and the more structured improvisation (and regular beat) of The Electricka Zoo and Ascension Band.
Further listening:
‘The Slab Septet’ tracks are an expanded lineup of Simon O’Rorke’s regular improvising trio from the late 90s / early 2000s, who can be heard here:
while the more recent Confluence tracks featuring Chris Prosser, Julie Bevan and Michael Hall can be heard here:

Simon O’Rorke also appears on the fiffdimension albums The Marion Flow and Mantis Shaped and Worrying
and many more at www.simon.ororke.net
Paul Winstanley produced and performs on The Marion Flow and dAdApApa: Waiting for the Drummer
You can hear some of his solo bass synth playing here and much more at Eden Gully.
Blair Latham performs with, among others, La Idea Electrica and Arc Trio
Jeff Henderson is a prolific & influential improvisor and multi-instrumentalist, and is manager of the Audio Foundation in Auckland
Dan Beban is guitarist for Orchestra of Spheres, the Rubbernecks and many more, and manages the Pyramid Club in Wellington.
He also plays with Simon O’Rorke in The Slab and Secretaries on Standby (along with Atsushi Iseki from the Ascension Band)
I’ve also dabbled with free improvisation at other times, including playing at Vitamin S events in Auckland
and with various one-off spontaneous groups in Wellington and elsewhere
At other times I’ve used free improvisations as raw material, which has been edited and multitracked into retrospective compositions – not so much cheating as a whole other topic…
